I want to integrate SD card (SPI intreface) with 7" touch panel (SPI+I2C).
Or another way is USB access to USB flashdisk (HOST,I don't need USB serial DEVICE).
Now I'm waiting for SPI display from China...
How can I detect full input buffer for GCODE (JSON) commands?
I'm using Arduino DUE with XYZ axis+one rotary axe.

From the original Synthetos forum (2011–2025)
I'll assume you are building upon tinyG2.
Your resources for info are the G2 wiki and the tinyG wiki
The buffer status is discussed here:
https://github.com/synthetos/TinyG/wiki/Tinyg-Communications-Programming#flow-control-options
An open source implementation similar to what you are doing is Chilipeppr.
CP runs with tinyG2 as well as tinyG.
Interesting project - Good luck!
I have full access to TinyG2 board, so I don't need access it by USB CDC.
mp_get_planner_buffers_available() is right way (I think).
Now I need move all texts,warnings,messages from USB CDC to classic UART?
How can I remap stderr FROM USB to UART->TX1 on TinyG2?
Bronek -- is the source for your modifications to G2 available? I'm looking at doing the same thing. I've seen your YouTube video -- looks great! :o)
